We have constructed and successfully laboratory tested a device that can periodically change from a submerged to a buoyant state using gas generated by microbes alone. The duration of the buoyant state and the switching frequency from the submerged to buoyant state can be controlled. If the type of microbes used is native to the deployment location, gas generation will not create an identifiable acoustic signature disclose the presence and operation of the device. In this report, we discuss the operation and testing of the device, the microbes that we use to test the operation of the device, and the test results.
